RESUMO
The article analyzes an experience with creation of different variants of arteriovenous fistulas (AVF) for the extrahepatic purification of blood by using the humeral artery. The above mentioned AVFs were shown to be expedient in patients with small diameters of the forearm vessels or in cases with no possibility to make AVF in the forearm. It is better to make AVF with the antegrade blood flow in the veins. The use of vascular transplants is indicated when there are no veins in the upper extremity suitable for AVF.

The authors have analyzed causes of disturbances of functions of arterio-venous fistulas (AVF) for chronic hemodialysis in 30 patients requiring repeated operations (fistula thromboses, suppurations, slow blood flow in the vein etc.). They recommend a preserving method of treatment of complications in AVF. Different variants of repeated operations are described depending on the individual cause of disturbances of the AVF functions.
